A To all whom it may concern:

WILLIAM iv FLETCHER, or IBINGRI-IAMTON, NEW YORK.

'Be it known that I, WILLIAM M. FLETCII ER, a citizen of the UnitedStates, residing at Binghamton, in the county of Broome and State of NewYork, have invented a certain new and useful Improvement in Horseshoes,of which the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings,

which form a part of this specification.

My invention relates to that class of horseshoes which are provided withdetachable calks having shanks which fit into apertures in the shoeproper.

In horseshoes of this class it has been customary heretofore to have theparts which secure the calks to the shoe project and I have found inpractice. that such projecting parts are apt tobe broken when the horseis .tramping over rough pavements or else bent so as to make itdifficult to remove and replace the calks when these are worn out. n

The object of my invention is to overcome this difficulty by soconstructing the members which hold the calks in place that thesemembers shall not project beyond the shoe, and by providing guards forprotecting and partly inclosing the means which keep the said membersfrom slipping out of their normal places.

Reference is to be had to theaccompanying drawings forming part of thisspecification in which Flgure 1 is a bottom view of a horseshoeconstructed in accordance with my invention; Fig. 2 is a sectional viewtaken on the line 22 of Fig. 1, and looking inv the direction indicatedby the arrow; Fig. 3 is an elevation looking from the toe of the'shoe,and Fig. 4 is a detail sectional view showing a modified form of heelcalk.

In the drawings, the body A of thehorse-v shoe is provided with suitablyarranged vertical holes B B for'receiving the shanks C C of the calks DD, these shanks and the holes for the same being preferably oblonginsection. The shoe is also provided with horizontal Miles E E passingthrough the walls of the shoe on opposite sides of each of the verticalholes B B, these horizontal holes being preferably round in section andof uniform diameter. I also provide holes F F in each calk, these holescorresponding in diameter to the holes E E in the shoe and being soplaced as toaline or.

register with the holes E E whenthe calks are slipped into their normalplaces. Tubular fastening pins G G are slipped through these alinedholes E F E and E F E,

these pins being preferably of steel and not long enough to projectbeyond the edge of the shoe at each end. Through the bore of proachclose to each other within the bore of the tubular pin.

It will readily be seen that by my construction the retaining members HH are protected against mechanical injury by being run in the groovesand that the tubular fasteningpins themselves are entirely inclosedwithin the shoe and calk, thereby protecting them from injury. When itis desired to replace the calk, the wires H II can easily be pried outwith any sharp tool, thereby releasing the pins G G which can then bedriven out with a nail.

For heel calks I have found a single such through the single calk asshown in Fig. 1.

Having thus described my invention, what I claim as new and desire tocover by Let'- ters Patent is 1. A horseshoe including a shoe body provided with a vertical perforation and with horizontal perforationsopening into the vertical perforation; a calk having a shank to fit thevertical perforation, said shank having a perforation alining with thehorizontal perforations when the shank is positioned in the aforesaidvertical perforation;

a tubular pin passing through the alined openings in the shank sternand'shoe body and a retaining member passing through the tubular pin andaround an adjoining part of the shoe body to hold the said tubular pinin place. i

2. A horseshoe including a shoe body provided with a Verticalperforation and with horizontal perforations opening into the verticalperforation; a calk having a shank to fit the vertical perforation, saidshank having a perforation alining with the horizontal perforations whenthe shank is positioned in the aforesaid vertical perforation;

a tubular pin passing through the alined In Witness whereof, I havehereunto set openings in the shank stem and shoe body; my hand, this18th day of July A. D. 1911, 10 and a retaining member passing throughthe 1n the presence of tWo subscribing Witnesses.
